To all whom it may concern:

'Be it known that I, Knrrn STEwjAn'r, a

in the art to which: it appertains toimake and use? the same..-.

The invention. relates: to improvements in spinning and fwinding machines in; which the thread fromthe. drawing; rollers is wound direct on toz-the. spindle. to form cops, with the object-of avoidingthe time and labor, and cost of bobbins, involved in the use of. separate cop-winding-ma l lower end-being mounted in a step bearing a having a't'emper blockc or other knowntempering means. The step bearing, is freechines.

The invention also relates to spinning, and I f winding frames in which eachspindle' is provided with a rapidly} rotated inverted slit cop-building cone carried by va coeaxial sleeve and fitted with a thread guide on its outer-surface and also with a, traversing 7 7 guide mounted on a, vertically sliding 'colflar rotating with the sleeve,the arrangement being suchthat as the, thread is woundv on; the spindlethe latter gradually risesuntil,

when the winding is completed, the cone is arrested. In a quill winder similar tothe.

above described type of winding frame, the arrest of theouter cop-building and thread guiding means has been effectedyautomatr cally by a kick-0E rod, connected with a- -cap in the head of the spindle, engaging with a belt striking device by which the driving belt was shifted from a fast'to aloose pulley.

Accordlng to the invention the sleeve clutch member adapted to engage with a member being held, in and out of engagement with the driving clutch member by a spring catch capable of being releasedby a handle or automatically by-a kick-off rod rising with the spindle. The thread traverse guide is reciprocated by an eccentric acting through a forked lever. A forked thread guide arm is pivoted above the sp1ndle,'so

is mounted on the; top of the; spindle the novel characteristic. feature of which is thatthe guldeslots for the thread penetrate into.v gu de, eyes adapted to. receive the ,thread- VK'IEIT'H s'rnwAnr, or. ca avan.Bammmmaa I Specification tfmeisma t "Patefited Dee 13, 19 21. 7

tions of the cone and its collar. 7 I

The said slot j mayrpreferablyibe in the the pulley 0, instead of beingstraight "as shown, with the object of eliminating strain on the thread. I I

For the usual eyeboard I preferably substitute a thread guide comprising a two armed-lever pivoted at r on the eycboard shaft,-the arm 1 having a slot 9 through which the thread is passed between the drawing roller and the guide pulley 0. The arm '1' makes contact with the end of a kick-off rod .9 operated from the step bush '0 so that the arm 1" is raised thereby out of the path of the rising spindle.

in a horizontal plane, and having one or more thread guide eyes vwhi'ch communicate with the periphery ofthe diskby open ended slots. The kick-off rod isso adjusted that at the moment the arm 1" of the thread guide leaves the thread, the spindle has risen to such aheight thatthe circumference of the disk at makes contact with the thread, which then slips into one ,or the other of the peripheral slots 1".

In modification of the two armed thread guide shown-in Figs. 1 and 3 of-the drawings and referred to as r, r and r, the arm 1- may be rigidly attached at right angles to the rod 8' which then becomes a lifting rod and maintains the thread guide 1" constant distance above the top of the spin ymy hand in presence of two witnesses.
